ABSTRACT:
A method of fabricating an ink jet head having a metal chamber layer includes preparing a substrate having pressure-generating elements to generate pressure to eject ink ejection. The metal chamber layer to define sidewalls of an ink flow path is then formed on the substrate. A sacrificial layer is formed to fill a region where the ink flow path is to be formed between the sidewalls defined by the metal chamber layer. A nozzle layer having nozzles corresponding to the pressure-generating elements is formed on the metal chamber layer and the sacrificial layer.
